A report released Thursday by the Canadian Antarctic Survey and Canadian Natural Resources said melting ice could cause a “catastrophic” effect on the planet’s oceans.
The report says that unless a solution is found quickly, the melting of the Greenland ice sheet could affect the global oceans, affecting the entire marine environment.
The ice sheet covers the Arctic Ocean and is considered one of the most significant threats to the oceans.
It is estimated to have lost almost 1.5 billion tonnes of ice since the beginning of the century, and scientists say the ice is melting at an alarming rate.
But a report released last week by the National Academy of Sciences said it’s possible that Greenland could lose about a fifth of its ice in a few decades.
The study found that as the ice sheets retreat, the amount of sea ice on Earth would decrease, but it said it is still uncertain whether this would result in a global loss of ice.
It found that in the next 30 years, as the glaciers on Greenland melt, sea level will rise about four metres and sea levels in the North Atlantic Ocean would rise an additional 1.4 metres.
“The consequences of a major ice sheet melt could be profound, with consequences for coastal cities, coastal wetlands, the oceans, sea-level rise, and coastal erosion, among other impacts,” said the report.
The authors said that while the melting and melting of ice sheets could have devastating impacts on global sea levels, it’s difficult to quantify precisely the impacts and their impact on ecosystems.
They said the potential impacts for many species, like whales, dolphins, and sea turtles, are not clear.
“It is uncertain whether the impacts would be large enough to lead to widespread extinction,” the report said.
But the report noted that the melting could lead to the rapid disappearance of ice in the oceans and sea ice is the main indicator of ocean acidification.
The researchers said the Arctic is already seeing signs of the effect of ice melting.
The Arctic is also the home of some of the world’s largest marine ecosystems, including the world is the home to one of our most productive fisheries and one of most productive harvests, said Dr. David Begg, the director of the Department of Geography at Dalhousie University.
“We know that in some places, there are a lot of species that can go extinct,” Begg said.
“There’s a lot to lose.”
The report said a significant proportion of the Arctic’s ice could disappear in a couple of decades, with the loss of up to 30 per cent of the area.
The loss of the Antarctic ice sheet is not clear, as its location is unknown.
The melting of Greenland could increase sea levels by 1.7 metres in a decade, according to the report, and the loss could lead ocean currents and currents of the sea to slow.
“Rapidly melting ice sheets can cause the sea level to rise rapidly, which can lead to coastal erosion and flooding, particularly in coastal regions, and to a decrease in the productivity of many fisheries,” said study author Dr. Scott A. Mowat, a glaciologist at Dalawie University in Nova Scotia.
The polar ice caps, which have been melting at a rapid rate for the past few decades, are also vulnerable to the impacts of climate change.
They are melting at rates of 0.8 per cent per decade.
“They are a major sink for ocean heat, which is a major contributor to sea level rise,” Moway said.
The National Oceanic and Atmospheric Administration is also monitoring changes in the ice sheet, and has said that changes in ice sheets will impact climate.
But its researchers said that the rate at which the ice has melted and the rate of the melting is also changing.
The Greenland ice cap has lost an average of 0,848 square kilometres (9,819 square miles) per year over the last century, with an average loss of 1.2 square kilometres per year, according the report by the researchers.
The average rate of loss is about 1 square kilometre per year.
Scientists say it’s important to understand the process that’s taking place to make decisions about what happens next.
“In a lot more ways, the world will be better off if we learn from what happened in Greenland,” said Professor Chris Field, from the University of Leeds.
